CL-OTH-SHEARINQ MACHINE.

SPECIFICATION forming part of Letters Patent No. 265,882, dated October 10, 1882.

Application filed March 29, 1882. (No model.)

To all whom it may concern:

Be it known that I, J. HARPER SMITH, a citizen of the United States, residing at Raritan, in the county of Somerset and State of New Jersey, have invented certain new and useful Improvements in Cloth-Shearing Machines, of which the following is a specification.

This invention relates to that class of machines for cutting figures or designs upon cloth in which a relief-pattern upon arevolvingclothsupporting roller projects the surface of the cloth to meet the cutters. Its objectis to produce upon the cloth, with one set of similarlynotched blades and a stationary or a longitudinally-reciprocating pattern -roll, a large number of clearly-cut, accurate, and uniform designs byprojectinginto the path ofa notched ledger or notched revolving cutters only a surface of the cloth corresponding to the pattern projecting from the surface of the pattern-roll. This object is accomplished by the combination of a notched ledger-blade with the patternroller, or by the combination of a notched revolving cutter with the pattern-roller, or by the combinatiomof a notched ledger-blade, a notched revolving cutter, and a pattern-roll. A briefmention of the possibility ofusing some of the above-stated combinations in cutting designs was made in the patent granted to me November 22, 1881; but the same were not claimed therein.

The invention is illustrated in the accompanying drawings, in which Figure l is a longitudinal vertical section of the machine, taken on line .17 00 of Fig. 2. Fig. 2 is a rear view of the same with some of the parts in section. Fig. 3 is a top view of one of the simplest forms of pattern-roll and a notched ledger-blade detached from the machine. Fig. 4 represents a sample of cloth having a design cut by the machine carrying the pattern-roll and either a reciprocating notched ledger-blade, as shown in Fig. 3, or a reciprocating notched revolving cutter, as in Fig. 2. Fig. 5 is a side view of the machine, showing the arrangement ofgearwheels, pulleys, belts, and operating-levers. Fig. 6 represents in relative position, but detached from the machine, the combination of a notched revolving cutter, a notched ledgerblade, and a pattern-roll, eachof these parts being provided with means to receive a longitudinal reciprocating motion. Fig. 7 represents a sample of cloth having a design cut with the elements as combined in Fig. 6.

Heretofore the following elements have been combined in different cloth-shearin g machines, viz: A notched revolving and reciprocating cutter, a stationary ledger blade, plain or notched, and a cloth-rest having an acute edge, a notched cloth-rest having an acute edge, with a plain or notched revolving cutter, and a plain revolving cutter with a pattern-roll; but these com binations differfrom mine, as well as their capabilities to produce a very large number of different designs-with the same cutting-blades.

My invention will first be described in connection with the drawings and then pointed out in the claims.

In the drawings, A represents the frame of the machine. B represents an adjustable frame hinged at b to the main part of the frame, said frame B carrying the revolving cutter G and the led ger-blade D.

E represents the pattern-roll. It is supported along its length by the roll F, and the latter is sustained at intervening points upon small rollers g,journaled in adjustable boxes G, supported by screws g, projecting from the platform A of the main frame.

The cloth to be operated upon passes first upon the roll it, over the pattern-roll E, under a guide-roll, h, to the cloth-drawing roller I. The latter having upon its surface a large number of fine points to engage with the cloth, it is positively connected with the pattern-roll E by means ofgear-wheels IKLFF E (Shown by full lines in Fig. 2, dotted circles in Fig. 1, and fully described in my patent above mentioned.) The'rolls E and F are partly inclosed in a casing, J. The forward end oft-he frame B is adjustably supported and connected with the frame A by means of boltsf, provided with jam-nuts f, placed upon said bolts above and under the horizontal portion of the frame 13. The revolving cutter O is mounted in the frame B in such a manner thatit can be reciprocated longitudinally in its bearings. The ledgerblade D rests upon brackets forming a. part of the frame B, and is also capable of longitudinally-reciprocating movement, being retained on said brackets by means of screws 1), passing through slots 01, made adjoining each end of the ledger-blade, the latter being provided with a stem, d, at one end, and this stem with the grooved collar (1 to receive a forked lever, D, to reciprocate it. The shaft of the revolving cutter O is also provided with a grooved collar, 0, to receive a similar reciprocating lever, O. The pattern-roll E is supported in bearings secured to the frame A, and is also capable of a longitudinally-reciprocating motion, while its gear E remains meshing with the gear F. 'To give to the pattern-roll this reciprocating motion one end of its shaft is provided with the grooved collar 0 to receive one end of the operating forked lever E. The levers O-D E are oscillated by means of grooved cams O D E, placed upon the shaft M of the machine.

Power is applied to machine by means of a,

belt passing over a pulley, M, upon the shaft M. This shaft transmits motion by means ofover guide-rolls m, mounted upon the ends of cloth maythusbemodified. The design shown in Fig. 4 can be produced by reciprocating either the revolving cutter or the led ger-blade whilethe pattern-rollis simply revolving. The pattern shown in Fig. 7 is produced by reciprocating the revolving cutter and 'the ledgerblade in one direction while the patternroll is reciprocated in the opposite direction, the series of small dots or small diamonds shown in Fig. 7 being made by the narrow cuttingedges of the notched portion of the revolving cutter coming for a brief space of time in contact with the portion of the cloth raised by the narrow pattern-rings projecting from the time or position of one or more of the cams C D E operating the parts by means of their oscillating levers.

Having now fully described myinvention, I claim- 1.. The combination of a ledger-blade, a notched revolving cutter, andapattern-roll directly under said revolving cutter, and adapted to elevate portions of a cloth-surface against said notched revolving cutter, substantially as and for the purpose described.

2. The combination of a notched ledgerblade, a revolving cutter, and a pattern-roll adapted to elevate portions of a cloth-surface against the revolving cutter, substantially as and for the purpose described.

3. The combination of a notched ledgerblade, a notched revolving cutter, and a pattern-roll adapted to elevate portions of a clothsurface against the revolving cutter, substantially as and for the purposes described.

4.. The combination ofa reciprocated led gerblade, a revolving cutter,and a pattern-roll, with mechanism foroperating the pattern-roll, substantially as and for the purpose described.

5. The combination of a ledger-blade, a revolvin g cutter, and a reciprocated pattern-roll, with suitable mechanism for operating the pattern-roll, substantially as and for the purposes described.

6. The combination of a reciprocated led gerblade, a revolving cutter, and a reciprocated pattern-roll, with suitable mechanism for operating the pattern-roll, substahtially as and for the purpose described.

7. The combination of a reciprocated ledgerblade, a reciprocated revolving cutter, and a reciprocated pattern-roll, with suitable mechanism for-operating the pattern-roll, substantially as and for the purposes set forth.
